  • Patent number: 11958870
    Abstract: An asymmetric tetradentate metal complex of a N{circumflex over (?)}C{circumflex over (?)}C{circumflex over (?)}N comprising tetradentate ligand has a metal connected to binding sites which are connected to each other via three or four covalent bonds that can be either single or double bonds with bridging linkers reside between C{circumflex over (?)}C and C{circumflex over (?)}N moieties. These linkers result in three-dimension metal complexes with distorted square planar geometries. The four donor atoms coordinate to a metal center. Upon metal binding a 5-6-6 membered metallocycle is formed upon chelation including a first nitrogen donor bond, a first metal-carbon bond, a second metal-carbon bond, and a second nitrogen donor bond. The light emission from these metal complexes can be tuned by the ligand structure over the entire visible spectrum.

  • Patent number: 11847435
    Abstract: Feedback-directed pass pipeline optimization in static compilation includes receiving a set of source input of source code by a static compiler. The static compiler initiates a compilation operation on the source code in which, in a pass pipeline during the compilation operation that creates an intermediate representation (IR) representing the source code, a set of optimization diagnostics identified during a first pass of the pass pipeline is emitted into a side file. The pass pipeline is then optimized using the set of optimization diagnostics.

  • Publication number: 20230195434
    Abstract: Code pattern matching is performed within computer code to determine whether the computer code includes an idiom from a predefined set of idioms. Based on determining that the computer code includes the idiom, a set of data items of the idiom to be analyzed is determined. The set of data items is analyzed with respect to one or more corresponding values from the computer code based on a set of constraints defined for the idiom to determine whether the set of data items satisfy one or more predefined conditions for the idiom. Based on the analyzing indicating that the one or more predefined conditions are satisfied, one or more code segments of the computer code including the idiom are replaced with replacement code to provide revised computer code.

  • Publication number: 20230178507
    Abstract: This disclosure relates to a new package concept that eliminates the need for epoxy or epoxy solder used in traditional clip/lead frame-based power packages. The disclosure overcomes this disadvantage in clip-based packages by depositing the interconnect structure directly to the bod pads. The formation of the interconnect done at lower temperature leads to lower stress induced onto the die. Another advantage of the present disclosure is that semiconductor dies packaged using a method according to the present disclosure will have smaller footprint as the pads are directly built up/deposited. Another advantage of the method according to the present disclosure is that it allows large scale, i.e., panel level processing. Such a panel may include multiple ICs, or transistor or any other semiconductor devices.

  • Patent number: 11630654
    Abstract: Aspects include modeling data cache utilization for each loop in a loop nest; estimating total data cache lines fetched in one iteration of the loop; and determining the possibility of data cache reuse across loop iterations using data cache lines fetched and associativity constraints. Aspects also include estimating, for memory reference pairs, reuse by one reference of data cache line fetched by another; estimating total number of cache misses for all iterations of the loop; and estimating total number of cache misses of a reference for iterations of a next outer loop as equal to total cache misses for an entire inner loop. Aspects further include estimating memory cost of a loop unroll and jam transformation, without performing the transformation; and extending a data cache model to estimate best unroll-and-jam factors for the loop nest, capable of minimizing total cache misses incurred by the memory references in the loop body.
